Vegetable landscape

Have you noticed this new trend of using vegetables to landscape? I have seen this all over and I think it's wonderful. This shopping center used tomatoes, cabbage, various herbs and annuals to make a colorful and clever garden. It sits right across from a popular burger joint. Could it be a way to encourage appetite? Though the question I have is who gets to eat the produce? I figure if you see that it's ripe it's yours. Somehow that may not be the case but we can hope.
